请问datagridview的网格线的问题

[xiaozi141]

我想修改列的网格线的颜色，就是竖着的线的颜色，而且想设置每列之间的线的颜色不一致，我式了一下gridcolor貌似不行..麻烦哪位大虾指导下我，谢谢~

好像得自己绘制。。。。

// Change the Border and Gridline Styles in the Windows Forms DataGridView ControlSamples:

this.dataGridView1.GridColor = Color.BlueViolet;  
this.dataGridView1.BorderStyle = BorderStyle.Fixed3D;  
this.dataGridView1.CellBorderStyle = DataGridViewCellBorderStyle.None;  
this.dataGridView1.RowHeadersBorderStyle = DataGridViewHeaderBorderStyle.Single;  
this.dataGridView1.ColumnHeadersBorderStyle = DataGridViewHeaderBorderStyle.Single;

只能自己画了，datagridview绘制的时候，是按单元格来绘制的矩形，按你的要求就是绘制矩形的左右边框颜色不同了
给你一段代码是绘制行头和列头的

protected override void OnCellPainting(System.Windows.Forms.DataGridViewCellPaintingEventArgs e)
{
Color mLinearColor1 = Color.FromArgb(248, 250, 251);
Color mLinearColor2 = Color.FromArgb(196, 207, 224);
Color mGridColor = Color.FromArgb(120, 147, 191); //网格线的颜色
Color mHasFocusedColor = Color.DarkCyan; //控件的焦点框颜色


Rectangle Rect = new Rectangle(e.CellBounds.X - 1, e.CellBounds.Y, e.CellBounds.Width, e.CellBounds.Height - 1);
LinearGradientBrush LinearGradientBrushs = new LinearGradientBrush(Rect, mLinearColor1, mLinearColor2, LinearGradientMode.Vertical);



try
{
if (e.RowIndex == -1 || e.ColumnIndex == -1)
{
e.Graphics.FillRectangle(LinearGradientBrushs, Rect);
e.Graphics.DrawRectangle(new Pen(mGridColor), Rect);
e.PaintContent(e.CellBounds);
e.Handled = true;
}
}

catch
{ }
finally
{
if (LinearGradientBrushs != null)
{
LinearGradientBrushs.Dispose();
}

}

/*不显示焦点颜色*/
this.DefaultCellStyle.SelectionBackColor = Color.Transparent ;
this.DefaultCellStyle.SelectionForeColor = Color.Black ;


base.OnCellPainting(e);
}
